Subject: Your feature on my blog

Hey {{first_name}},
I’ve been a fan of what you’ve been doing with {{company}} over the past couple of years.
I’m reaching out because I’m working on a new piece geared towards [[topic of the blog post you’re writing]] from those who’ve already been through this experience themselves and I’d love to hear your take on it. The post will be publishing to my blog [[optional—that gets x # of readers]] and I’d love to get a quick quote from you to include in the piece if you’re up for it.
If you’d be able to answer this question in a few sentences, that would be amazing:
[[Relevant question/challenge that will give them an opportunity to showcase their expertise]]

How do you advise people on overcoming that challenge?
[[Your Name]]
